prone-to-crouch transitions

[isoFlux]

i like Ghost Recon\'s method of changing posture.

three postions:
prone - crouch - stand

there are just two buttons: raise posture, and lower posture.

if you are crouched, and you hit lower posture, you go to prone, if you are in prone and hit raise posture you go to crouch. but if you are standing, and hit lower posture twice in succession, you drop directly to prone, and vice versa. very fluid.

i tried to make scripts to do this in RO and TTR, but in RO if you deployed your weapon while prone, it screwed it up. and i forgot if it worked or not in TTR. i should try it again.
